MIT labs win top recognition for sustainable practices in cold storage management

In its fourth calendar year, the Intercontinental Institute for Sustainable Laboratories (I2SL) Intercontinental Laboratory Freezer Problem drew 218 laboratory members from all-around the entire world, from 88 investigation establishments. Three MIT laboratories participated in the obstacle: the Section of Biology’s Barbara Imperiali Lab, Department of Biological Engineering’s Jacquin Niles Lab, and Section of Biology/Whitehead Institute for Biomedical Research’s David Sabatini Lab. MIT and the Whitehead Institute collectively gained the Best Academic Firm Award. The Niles lab and the Imperiali lab are MIT Natural environment, Well being & Protection (EHS) Eco-friendly Lab Licensed.

The Freezer Challenge, which is operate by the nonprofit companies My Eco-friendly Labs and I2SL, is aimed at endorsing efficient, powerful sample storage for laboratories close to the environment, and applying a spirit of friendly competition to maximize sample accessibility, sample integrity, lowered prices, and energy performance.

In excess of a 5-month interval, challenge contestants put into action best cold storage administration practices, this sort of as defrosting and removing dust from freezer ingestion or coils, common cleanouts, firm of stock on file, and large-density storage. Winners are then decided on based mostly on the amount of electricity saved. On top of that, in the spirit of helpful competition and collaboration that pervades the challenge, contestants can get paid points for sharing strategies about their own cold storage very best procedures.

This year, the 218 laboratory individuals saved an estimated full of 3.2 million kilowatt-several hours (kWh) for every year, up from 2.4 million in 2019. The discounts signifies the equal of minimizing carbon emissions by 2,260 metric tons per 12 months, or removing 360 passenger autos from the road for a year. In accordance to Christina Greever, functions manager at My Green Labs, the three participating MIT and Whitehead Institute labs saved an estimated 520 kWh/yr.

Two of the a few labs — Niles and Imperiali — have formerly participated in MIT EHS’ Green Labs Freezer Obstacle, and have therefore instituted excellent management procedures bordering cold storage. The Sabatini lab has not formerly participated in EHS’ obstacle, but had also already executed quite a few of the methods the obstacle encourages and benefits.

Edith Valeri, of the Sabatini lab, mentioned that although her lab did not confront any main complications, the obstacle inspired lab administration staff members to be “more conscious of freezer usage” and “more mindful of wattage utilization, turning down temperatures to a sustainable degree, and defrosting the freezers.”

Similarly, both equally Sebastian Smick, a technical affiliate in the Niles lab, and Christine Arbour, an NIH postdoc in the Imperiali lab, observed that taking part in the challenge was not disruptive to functions, and the only problems they ran into arrived as a consequence of the Covid response. Mainly because of their prior participation in the MIT EHS’ Eco-friendly Labs Freezer Challenge, productive strength use is now routine for the three labs.

Smick explained the challenge as “a superior incentive” for the Niles lab to exercise common thawing, and “a nice way to quantify what it usually means to the University’s electric power usage.” He credits MIT Custodial Products and services for the invaluable help they provide on a regular foundation. “Custodial Companies is always there for us for the duration of our thaws to supply mopping and absorbent barriers while we thaw. Most of the ice is captured as a solid, but spillover is unavoidable. They’ve saved us hundreds of paper towels!”

The Imperiali lab upgraded its chilly storage in March, changing its minus-80 levels Celsius freezer with a newer, additional electricity efficient product, and entered the obstacle completely ready to aim on maximizing that expense. “Our lab continually cleans our freezer filters, -80 diploma C freezer in individual, to protect against the compressor from overworking,” says Arbour. “We are also vigilant with ideal chemical storage. We retail outlet chemical substances at the temperature that the provider/enterprise recommends and nothing at all colder. This helps prevent overcrowding in –20 and –80 diploma C freezers, which can get started to increase up!”

For Smick, a vital takeaway from the problem was the quantification of the energy intake of his lab’s cold storage. “I was so surprised when I first learned about the energy consumption of our -80 C and -20 freezers,” he recalls. “It’s effortless to see the impression of switching to a less costly reagent or reducing a wasteful method when it is some thing that arrives right out of your pocket, but electric power is anything we acquire for granted it should really be conserved like any purely natural resource, and this problem genuinely shines an environmentally pleasant, zero-vitality usage gentle on how simple it is to make a substantial impact.”

Smick credits the challenge with inspiring his lab to carry out typical thaws, a big electrical power-preserving follow. “I know for a actuality that, prior to our common freezer thaws which we started performing simply because of this competitors, we have been throwing away hundreds of dollars of reagents absent each individual yr because they were misplaced in the glaciers that we ended up sustaining in our freezers.”

Likewise, Arbour says the Imperiali lab will continue on to implement the techniques identified in the challenge. “Our lab procedures will continue to evolve with new inexperienced procedures,” she says. “Our complete lab is invested in performing much better for the surroundings.”

“My hope is that competitions like this encourage MIT and the whole world to get a additional really serious search about how we deal with the sources offered to us: from electricity to recyclable waste,” suggests Smick. “Science generates a massive amount of money of squander, and there is so substantially a lot more that we can do to lower environmental impact, and to offset the expense of building meaningful details.”

MIT EHS has designs in the performs for the enhancement and expansion of the Institute’s Inexperienced Labs system, and will be employing them in the impending 12 months.
